2.5 Ton - 40,000 BTU - 80% AFUE - Downflow AC & Furnace Systems
3 matched systems, cheapest first. A 2.5 Ton system usually suits a home of roughly 1,250 to 1,500 square feet, paired here with a 40,000 BTU 80% AFUE downflow furnace. This is a standard efficiency furnace that vents through a metal flue. Every system ships with the outdoor unit and the matching indoor side together.
2 of these are marked "Northern states only." Federal efficiency rules let lower-SEER2 air conditioners be installed only in the northern half of the country. If you live in the South or Southwest, pick one without the tag, or call (877) 843-4822 and we will point you to the right one.
